Evolution of Communication and Monitoring Systems for the Management of Traffic and Safety Control Systems in Railway Sites

The collaboration between R.F.I. S.p.A. and Alma Mater Studiorum of Bologna had the purpose to evaluate the feasibility and to investigate the main radar sensor tech- nologies suited to be integrated with existing signalling systems in rail sites, with particular reference to the UWB technology. This activity has been supported by a study of the UWB radio channel characteristics in a reference (LC-like) scenario, through ray tracing (RT) simulation. It was also studied, with the aid of computer simulations, the remote interconnection of several radars via ?ber optic links (RoF), in order to concentrate in a single physical location all the signal processing operations and network control.
